Using an ethylene carbonate solvent with a sodium iodide salt to create a new kind of refrigerator

https://techxplore.com/news/2022-12-ethylene-carbonate-solvent-sodium-iodide.html

"ionocaloric refrigeration environmentally safe... repeatedly cooling a material also cool its environment by removing and adding back salt... added mixer to a box... another device performed electrodialysis to remove the salt... approximately as efficient as refrigerators now on the market. The big advantage of the approach is that it does not emit any hydrofluorocarbons or other pollutants. They acknowledge that it does have one drawback—it takes quite a while for the mixed solution to cool"
